Abstract (en)
[origin: US2009205843A1] Methods and apparatus include tubing expanded to create a seal in an annulus surrounding the tubing. The tubing includes a sealing material selected to cause forming of undulations in a diameter of the tubing upon expansion of the tubing. Various factors of the sealing material such as deviations in its thickness influence sealing performance of the tubing with the sealing material.
